Bug Bite, Parasite, or Something Else? Itchy raised bump with a trail
I’m wondering if anyone has ideas of what this could be?
Location: inner, upper, right arm.
I noticed it a few days ago because it was itchy. Not terribly, and not painful, I’d say equivalent to other non-concerning but bites of the past.
The circle part is about 1-1.5 inches in diameter, slightly raised, with a small puncture dot.
The trail is also slightly raised, about 2 inches in length and slightly itchy.
It does not seem to have gotten any larger or worse since I noticed it a few days ago, but the trail part freaked me out a bit.
This morning, I noticed the itching and redness has spread slightly to the back of my arm. Though I can’t say with certainty it’s part of the initial thingy, and the redness could easily be from scratching. I don’t see a full trail connecting it, but you know how dermatological google searches can incite fear.
